Crafting with Bamboo Crafty Tip Working with bamboo is different than working with wood. Instead of drilling bamboo I burn holes using heated steel rods of different dimensions. This cauterizes the hole and gives a clean seal all around it. Drilling can be done with very small bits, but the skin of the bamboo tends to pull up with the bit if it's too large. If using a drill use spur point or tile bits for a better result than a twist bit.
